King Charles and Queen Camilla have arrived in the US at the start of a four-day state visit - the first since Queen Elizabeth II's visit in 2007.
They arrived at Andrews military airbase in Maryland before being greeted at the White House by President Donald Trump and First Lady Melania Trump.
Security is extremely tight after the shooting incident in Washington DC at an event attended by the president on Saturday.
King Charles will address the US Congress on Tuesday and it is expected that he will express sympathy over the attack.
His speech is also expected to say that in times of great international challenges, it is more necessary than ever to stand together to defend democratic values.
